What ACRA is and why it exists
The Accounting and Corporate Regulatory Authority (ACRA) is Singapore's national regulator for business entities, public accountants, and corporate service providers. It was established under the Accounting and Corporate Regulatory Authority Act and operates as a statutory board under the Ministry of Finance. Its core job is to maintain the integrity of Singapore's business environment: registering companies, setting accounting and auditing standards, and enforcing compliance with the Companies Act and related legislation.
ACRA is not a tax authority - that's the Inland Revenue Authority of Singapore (IRAS). It's not a labour regulator either - that's the Ministry of Manpower (MOM). ACRA's focus is specifically on the legal existence and governance of business entities. If you want to understand how corporate tax obligations flow from your registered entity, IRAS is the next stop, but ACRA is where the entity itself begins.
BizFile+ and the public register of businesses
ACRA's primary interface with businesses and the public is BizFile+, its online portal at bizfile.gov.sg. This is where companies are incorporated, where changes to company details are filed, and where annual returns are submitted. It's also a public register: anyone can search for a Singapore-registered entity and see its registered name, Unique Entity Number (UEN), registered address, business activity, and the names of its directors and company secretary.
That transparency is deliberate. Singapore's regulatory model depends on accurate, publicly accessible corporate records. When a bank, a landlord, or a counterparty does due diligence on your company, BizFile+ is where they look. Keeping your records current isn't just a compliance tick-box - it's how your company presents itself to the world. You can read more about what a UEN number is and how you get one, since that identifier is assigned by ACRA at the point of registration.
What ACRA actually regulates and enforces
ACRA's remit covers three distinct groups. First, business entities: private limited companies, sole proprietorships, partnerships, and limited liability partnerships (LLPs) must all register with ACRA before commencing operations. Second, public accountants and accounting entities: ACRA sets the standards for auditing and financial reporting in Singapore and oversees the registration of public accountants. Third, corporate service providers (CSPs): firms that provide company secretarial, nominee director, or registered address services must themselves be registered with ACRA.
On the enforcement side, ACRA has real teeth. It can investigate entities and individuals who breach the Companies Act, issue penalties for late or inaccurate filings, and ultimately strike off companies that persistently fail to comply. The Registrar of Companies sits within ACRA and is the officer with formal authority over the company register.
Ongoing obligations every registered company carries
Registration is the start, not the finish. Once a company is on the ACRA register, a set of recurring obligations kicks in. Every Singapore-incorporated private limited company must appoint a company secretary within six months of incorporation, and that role can never be vacant for more than six months. The secretary must be ordinarily resident in Singapore, and a sole director cannot also serve as secretary.
Beyond the secretary requirement, companies must hold an Annual General Meeting (AGM) within the required timeframe, file an annual return with ACRA, and keep their registered particulars current. Changes to directors, the registered office address, share structure, or the company's financial year end all need to be lodged through BizFile+. Late filings attract penalties, and persistent non-compliance can escalate to enforcement action against directors. Our corporate secretarial services page covers how Duellix handles these obligations on your behalf.
How corporate service providers fit into the picture
Most founders - particularly those incorporating from overseas - work with an ACRA-registered corporate service provider (CSP) rather than filing directly. A CSP can act as the appointed company secretary, provide a registered office address, and handle routine and non-routine filings through BizFile+ on the company's behalf. The government fees are the same whether the company files itself or through a CSP, so what you're paying for is the expertise and the deadline management, not access to the portal.
Duellix Pte. Ltd. is an ACRA-registered corporate service provider (registration FA20240123, UEN 202136271N). That registration means Duellix is subject to ACRA's own oversight as a CSP, which includes anti-money laundering obligations and fit-and-proper requirements for the firm and its personnel. If you're looking at company registration for the first time, working with a registered CSP is the most straightforward route.
Every Singapore company exists, legally speaking, because ACRA says it does, and it stays compliant only as long as ACRA's records reflect reality.
How ACRA obligations work in practice
Register the business with ACRA before operating
No business entity in Singapore can legally commence operations without first registering with ACRA. For a private limited company, this means reserving a company name, preparing a company constitution, and filing the incorporation application through BizFile+. ACRA assigns a Unique Entity Number (UEN) upon successful registration, which becomes the company's permanent identifier across all government agencies. You can read more about how the UEN works and what it's used for.
Appoint a company secretary within six months
Once incorporated, the company must appoint a qualified company secretary within six months. The secretary must be ordinarily resident in Singapore, and a sole director cannot fill the role themselves. The secretary's name is recorded on the ACRA register and is publicly visible on BizFile+. This is a statutory requirement under the Companies Act, not an optional administrative convenience. Our corporate secretarial services page explains what the role covers in practice.
Keep company particulars current on BizFile+
Any change to the company's registered details - a new director, a change of address, an update to the business activity description, or a change in share structure - must be filed with ACRA through BizFile+. These updates are not optional and must be lodged promptly. ACRA's register is a live public record, and inaccurate information can create problems with banks, counterparties, and government agencies that rely on it. The Registrar of Companies has the authority to query or act on discrepancies.
Hold the AGM and file the annual return
Each financial year, a Singapore private limited company must hold an Annual General Meeting (AGM) and file an annual return with ACRA. The annual return confirms that the company's statutory records are in order and that the information on the register remains accurate. Late filing attracts penalties, and ACRA can escalate to enforcement action against directors for persistent non-compliance. Extensions are available in some circumstances but must be applied for before the deadline, not after.
Comply with accounting and reporting standards
ACRA sets the financial reporting standards that Singapore companies must follow, based on the Singapore Financial Reporting Standards (SFRS). Companies are required to prepare financial statements that comply with these standards. Smaller companies may qualify for audit exemptions, but the obligation to prepare accounts remains. These accounts feed into the annual return filing and, separately, into corporate tax filings with IRAS. Our corporate tax services page covers how the two obligations connect.
Benefits
Single register for all business entities
ACRA maintains one authoritative public register covering private limited companies, sole proprietorships, partnerships, and LLPs. BizFile+ gives anyone instant access to a company's registered details, making due diligence straightforward for banks, counterparties, and government agencies.
Statutory deadlines are fixed and enforceable
ACRA's compliance calendar is not discretionary. Annual returns, AGMs, and officer appointments all carry legal deadlines under the Companies Act, with penalties for late filing and the possibility of enforcement action against directors for persistent non-compliance.
Corporate service providers are themselves regulated
ACRA registers and oversees corporate service providers, which means the firm handling your secretarial and filing work is itself subject to regulatory scrutiny. An ACRA-registered CSP must meet fit-and-proper requirements and comply with anti-money laundering obligations, giving clients a baseline assurance about who they're working with.
Penalty appeal process exists for genuine cases
If a company incurs late-filing penalties, ACRA has a formal process for applying for a waiver or refund. The application must set out the reason for the delay and attach supporting documents, and ACRA typically takes four to eight weeks to review it, though the outcome is at ACRA's discretion.
ACRA obligations in real situations
Foreign founder incorporating a Singapore company remotely
An overseas entrepreneur setting up a Singapore private limited company must register with ACRA before the entity can open a bank account, sign contracts, or hire staff. Because ACRA requires at least one director who is ordinarily resident in Singapore, a foreign founder who isn't relocating will typically need a nominee director alongside their own directorship. The company secretary must also be Singapore-resident. Working with an ACRA-registered CSP covers both requirements in a single engagement. Once incorporated, the UEN assigned by ACRA becomes the company's identifier across CPF, IRAS, and every other government agency.
A company with overdue ACRA filings needing to catch up
A company that has missed annual return deadlines or failed to hold its AGM on time is in breach of the Companies Act. ACRA's late-filing penalties accrue on overdue filings, and the longer the delay, the higher the exposure. Catching up is always cheaper than the penalties, but it requires reviewing the statutory records, drafting any missing resolutions, and filing the outstanding returns in the correct sequence. ACRA also has a process for appealing penalty waivers, though the outcome is at ACRA's discretion and typically takes four to eight weeks to review.
An SME switching corporate secretarial providers
When a company changes its corporate secretary, the outgoing secretary's name must be removed from the ACRA register and the incoming secretary formally appointed - both through BizFile+. The statutory registers and minute book also need to transfer between providers. This is a routine ACRA filing, but it does require coordination between the outgoing and incoming CSPs. The company's ACRA record must reflect the new appointment accurately before the incoming secretary can act in that capacity. Our corporate secretarial services page explains how Duellix manages the handover.
A company filing its annual return alongside its tax obligations
The annual return filed with ACRA and the corporate tax return filed with IRAS are separate obligations with different deadlines, but they draw on the same underlying financial statements. A company that has its accounts prepared on time can meet both deadlines without duplication of effort. The ACRA annual return confirms the company's statutory status; the IRAS filing accounts for its taxable income. Understanding how the two interact helps founders plan their year-end compliance calendar. See our guide to corporate tax rates in Singapore for the tax side of this picture.
Common questions about ACRA
What does ACRA stand for and what does it do?
ACRA stands for the Accounting and Corporate Regulatory Authority. It is Singapore's national regulator responsible for registering and overseeing business entities, public accountants, and corporate service providers. It maintains the public register of companies and other business entities through BizFile+, sets accounting and auditing standards, and enforces compliance with the Companies Act.
Do I need to register with ACRA before my company can operate?
Yes. No business entity in Singapore can legally commence operations without first registering with ACRA. This applies to private limited companies, sole proprietorships, partnerships, and limited liability partnerships. Registration is done through ACRA's BizFile+ portal, and ACRA assigns a Unique Entity Number (UEN) upon successful registration.
What happens if my company misses ACRA filing deadlines?
Late lodgement penalties accrue on overdue filings, and persistent non-compliance can escalate to enforcement action against directors and ultimately to the company being struck off the register. ACRA does have a formal process for applying to waive or refund penalties, but the outcome is at ACRA's discretion and typically takes four to eight weeks to review.
Is Duellix registered with ACRA as a corporate service provider?
Yes. Duellix Pte. Ltd. is an ACRA-registered corporate service provider, registration FA20240123, UEN 202136271N. That registration means Duellix is subject to ACRA's own oversight requirements for CSPs, including anti-money laundering obligations and fit-and-proper standards.
Can a company director also act as the company secretary?
Not if they are the sole director. Under the Companies Act, a sole director cannot also appoint themselves as company secretary. The secretary must be ordinarily resident in Singapore. Where a company has more than one director, one of them may serve as secretary, subject to the residency requirement.
